This is the time in InuYasha's young life when Izayoi, his mother, died. This is also the time when the brothers got along.
InuYasha: Big Brother, why won't Mommy wake up?
Sesshomaru: She can't. She's gone.
InuYasha: But she will come back.
Sesshomaru: No, she's gone and can't come back.
InuYasha: Why, Big Brother, why?
Sesshomaru: InuYasha, she just...
InuYasha: Can you make her come back?
Sesshomaru: (starts to sniffle and shakes his head) Baby Brother, I can't. She's beyond my help.
InuYasha: This isn't fair. Mommy's supposed to play with me in the garden. Why, Mommy, why? Why did you go away?
Sesshomaru: (tears drip down his face) I...InuYasha.
InuYasha: Mommy, come back. (starts crying) MOMMY....!
